Successful surgical rehabilitation of children with traumatic corneal laceration and cataract.

OBJECTIVE: To evaluate the visual and refractive outcome of corneal transplant surgery, cataract extraction, and intraocular lens (IOL) implantation in children with traumatic corneal laceration and cataract. DESIGN: Retrospective, noncomparative case series. PARTICIPANTS: Five patients, 7 years of age or younger, who underwent penetrating keratoplasty, cataract extraction, and IOL implantation for traumatic corneal laceration and cataract were identified. MAIN OUTCOME MEASURES: Each case was analyzed retrospectively for the following factors: preoperative findings; surgical technique, including management of the posterior capsule; measurement of axial length and keratometry; calculation of IOL power, style, and type of IOL implanted; graft clarity; final visual acuity; and final refraction. RESULTS: The five children ranged from 3 to 7 years of age at the time of trauma. All had primary repair of their injury before referral. Each patient was observed for more than 2 years. Each had a posterior chamber IOL placed in the sulcus. After surgery, no severe complications were observed. The preoperative visual acuity ranged from 20/400 to light perception. After surgery, all five patients had clear grafts and an improved visual acuity ranging from 20/20 to 20/400. The final spherical refraction in each patient was within 3.75 diopters (D) of plano, with 1.50 to 3.25 D of cylinder. CONCLUSIONS: Successful surgical rehabilitation was accomplished in these patients. Despite their young age and the difficulty in determining IOL power, combining surgery and aggressive amblyopia therapy resulted in visual rehabilitation with refractions approaching emmetropia.

Nonsurgical management of binocular diplopia induced by macular pathology.

OBJECTIVE: To treat binocular diplopia secondary to macular pathology. METHODS: Seven patients underwent evaluation and treatment. All had constant vertical diplopia caused by various maculopathies, including subretinal neovascularization, epiretinal membrane, and central serous retinopathy. Visual acuity ranged from 20/20 to 20/30 in the affected eye. All except 1 patient had a small-angle, comitant hyperdeviation with no muscle paresis. Sensory evaluation demonstrated peripheral fusion and reduced stereoacuity. Neither prism correction nor manipulation of the refractive errors corrected the diplopia. A partially occlusive foil (Bangerter) of density ranging from 0.4 to 1.0 was placed in front of the affected eye to restore stable, single vision. RESULTS: The Bangerter foil eliminated the diplopia in all patients. Two patients elected not to wear the foil; 1 patient was afraid of becoming dependent, and the other was bothered by the visual blur. Visual acuity in the affected eye was reduced on average by 3 lines. All patients maintained the same level of sensory fusion, with only 2 having reduced stereoacuity. Symptoms returned when the foil was removed or its density was reduced. CONCLUSION: Low-density Bangerter foils provide an effective, inexpensive, and aesthetically acceptable management for refractory binocular diplopia induced by macular pathology, allowing peripheral fusion to be maintained.

Mortality rate in strabismus surgery.

Strabismus surgery has been viewed as being associated with a high degree of mortality. Many past studies have used small surgical samples and have stressed the various theoretical causes of the deaths rather than view the procedure from a statistical and scientific standpoint. We present here a large series of surgical cases collected nationwide showing that strabismus surgery is a relatively safe procedure associated with a mortality less than that of a tooth extraction.
